642687 divided by 10 
The aim is to understand the frequency of 10 in 642687.

Moving on to step 1:
The number 10 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 10

Going ahead to step 2:
When dividing 64 by 10, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 60 away from 64, we end up with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 10

Step 3:
10 goes into 42 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 64.0
Deduct 40 from 42 and we're left with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 10

Advancing to step 4:
10 goes into 26 2 times with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 642.0
Subtracting 20 from 26 leaves us with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 10

Moving on to step 5:
68 divided by 10 is 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 6426.0
Subtracting 60 from 68 leaves us with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 10

Step 6:
10 goes into 87 8 times with a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 64268.0
Subtracting 80 from 87 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
10 goes into 70 7 times with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 64268.7
Subtracting 70 from 70 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
10 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 64268.7
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
The number 10 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 64268.7
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 64268.7 with a remaining 0.0.
